Years back i was moving a downstairs radiator to another wall which necessitated taking up some floor boards (or what the builders had deemed suitable for walking on ) on the upstairs landing. My wife had said you will have this job finished before 5pm as you know my friends are coming round, yea yea i assured her and of she went to work. After a read of the paper and a cuppa (no rush easy job) i started to drain the central heating system down from one of the two downstairs radiator drain cocks but it had decided it was not going to function today. After mucking about with it for quite some time it still wouldnt open. So i tries the other drain after a bit of coaxing it opens and the system slowly starts to drain. I goes upstairs and opens the rad bleeders to increase the flow i then took the flooring up. I made myself another brew and waited for the the drain down to finish. Water all out i cuts the pipes upstairs moves the rad and puts the new pipework into place, i looks at my watch and its half twoish i thinks better get a move on she will be back about 3. So i prepare the pipe ends for the first joint and heat up the yorkshire fitting (solder ring) solder shows job done. I start wirewooling the pipes for the second joint i hears the missus get in, and you know the way they are, i thought you would have finished by now nag nag, yes dear, i hit a few snags but i will be finished in half an hour. By now she,s standing behind me with words of encouragement like i hope this is gonna be done your always the same etc, during this ear ache i puts the fitting in place and starts heating it up. After a bit no solders showed but i thinks maybe its showing underneath anyway by now i just want to finish so i go and turn the water on, wife still grumbling in the kitchen. Id had enough in the kitchen i goes and a couple of words are exchanged, after a few minutes i heads back for the stairs to check the job and shut the rad bleeders. Then i hears the sound of running water that you dont want to hear when youve just done a plumbing job as i get to the stairs im greeted by water coming down them. I ran up and its squirting everywere, its from that second joint. With all the argy bargy id forgot to flux the pipes, you should have seen the mess not to mention the wifes face. I dont think we spoke for a week afterwards
